Dwyer series 2000 magnehelic differential pressure gauge
2000-60pa,stainless steel
Introduction
Dial differential pressure gauges measure the difference in
pressure between two points in a system and display the measurement
on an analog dial display. Users can connect gauges with integral
switches to a control system to respond when the measured pressure
rises or falls below a set point. Gauges are available for use in
low-, medium-, and high-pressure systems.

Working principle
Based on the sensing element using two identical stiffness of the
bellows, therefore under the same measured medium forced it to
produce the same focus respectively on the legs, because of the
spring leaf waiting for a moment on both sides do not produce the
deflection, stent is still in the original position, the gear
transmission mechanism is not action,
make the pointer still refers to the zero When applying different pressure (general high pressure end is
higher than low pressure end), the force of two bellows acting on
the movable bracket is not equal, so that the corresponding
displacement is produced respectively, and drive the gear
transmission mechanism to drive and to enlarge, indicating the
differential pressure between the two after the pointer is deflect.
Performance characteristic
• Easy to read gage through undistorted plastic face permits
viewing from far away
• Patented design provides quick response to pressure changes means
no delay in assessing critical situations
• Durable and rugged housing and high-quality components combine to
provide long service life and minimized down-time
• High accuracy option is twice as accurate as the standard
Magnehelic® gage
